Retraction: Mobile phones not harmful to health fano

"Three" is a UMTS mobile telephone network. In an early post
was discussed what the current status of this technology. UMTS can operate in different frequencies from 824 to 2570 Mhz. However, in Italy, the frequency rates are employed by television, so do not stay that UMTS frequencies that are closest to the resonant frequency of water.
The Three, which only works with UMTS and HSDPA, it can not, for now, use the lower frequencies. This is one reason why they need three cards of recent phones that support UMTS.
Higher frequencies interact more with the matter. Are then easily screened by walls and roofs, and the signal coverage is affected. For more coverage in the Three leans roaming network Tim

GPS / GPRS / EDGE , which instead uses low frequencies. This scenario is

will change with the transition to digital terrestrial television. The television signals travel on these UHF frequencies that include the signals at 900 Mhz. The digital compared to analog, requires less bandwidth and thus shed new frequencies. An important step was taken in the European Union, which granted the frequencies around the 900 Mhz

for UMTS
. member states then have to complete assignments. In Italy, the three should win this frequency, in accordance with resolution "541/08 Cons., Art. 3, paragraph 2", this resolution states that: "5 MHz to 900 MHz are reserved for UMTS mobile operators only and any Managers mobile new entrants "As we
UMTS has written a very powerful signal. E 'to free up more frequencies around 2.4 GHz, which, among others, are also technically inappropriate. However, the most likely is that we will have broadband signals (very powerful and therefore very dangerous) at all frequencies. Very bad scenario for our health. But we have really fast internet everywhere.
